Which spare parts belong in a field kit?
We are building a spare parts kit for a deployed counter-drone system and the list from the vendor is enormous and expensive.
What actually fails in the field? I would rather stock the parts that cause downtime than the entire catalogue.

In our fleet the failure order is connectors, then antenna mounts, then power supplies, then everything else. Cables and connectors first, always.
That matches our experience. We now carry a full set of RF cables because a damaged one takes the whole node offline.
